We’ve made our Zip-in Front Panel to fit over the mesh panel of the main compartment of the “Just One” backpack.  You’ll find that the Just One is the most versatile pack you’ve ever owned, and little details like this will make it even better.  This panel will not only transform your pack into a conventional, fully enclosed backpack -- it’s also reversible.  So you can choose camo or high-visibility orange, based on the needs of the day.
